Health Screening 101: What to Expect and Why It Matters

Health screenings are one of the most effective ways to catch medical conditions early—before they become serious. These tests help identify potential health risks, guide treatment plans, and support overall well-being. While many people associate screenings with hospital visits, they are now more accessible than ever—even at your local pharmacy.

In this guide, you’ll learn what health screenings are, what to expect during a visit, and why staying on top of your health is easier (and more important) than you may think.

What Is a Health Screening?

A health screening is a simple test or check that looks for signs of a disease or condition before symptoms appear. The goal is early detection and prevention.

Screenings are usually quick, non-invasive, and may include:

• Blood pressure checks

• Blood sugar or cholesterol testing

• Body mass index (BMI) evaluations

• Vision or hearing assessments

• Bone density testing

Some tests can even be done at a pharmacy or during a regular wellness visit.

Why Health Screenings Matter

Early detection saves lives. Many chronic diseases—like heart disease, diabetes, and some cancers—develop slowly and without symptoms. Regular screenings can:

• Catch problems early, when they’re easier to treat

• Reduce the risk of complications

• Support healthier lifestyle choices

• Help your care team create a personalized plan

Even if you feel healthy, routine screenings give you valuable insights into your overall health.

Who Should Get Screened?

Health screenings are recommended for most adults, but how often and which tests you need depends on your:

• Age

• Family history

• Existing health conditions

• Lifestyle factors (such as smoking, diet, and activity level)

Here are some general guidelines:

In Your 20s–30s

• Blood pressure check every 2 years (more often if elevated)

• Cholesterol test every 4–6 years

• Blood glucose test if overweight or with family history of diabetes

• STI screenings if sexually active

In Your 40s–50s

• Continue routine screenings above

• Add screenings for colon cancer, diabetes, and bone density (based on risk factors)

60 and Over

• More frequent screenings for cardiovascular health

• Eye and hearing exams

• Osteoporosis and fall risk assessments

Talk to your pharmacist or healthcare provider about which screenings are right for you.

What to Expect During a Screening

Most screenings are quick and painless. Some may require a small blood sample or finger prick. Others use a cuff, scale, or monitor.

Here's what typically happens:

Blood Pressure Check

• A cuff is placed around your arm

• It inflates and deflates to measure pressure in your arteries

• Results are given in two numbers (systolic/diastolic)

Blood Sugar or Cholesterol Test

• A small drop of blood is taken from your finger

• Results may be available within minutes

• Fasting may be required depending on the type of test

BMI Screening

• Height and weight are measured

• Used to estimate body fat and assess risk for obesity-related conditions

Vision or Hearing Screening

• Simple tests using eye charts or sound tones

• May indicate a need for further evaluation

Tip: Wear comfortable clothing, bring a list of medications, and arrive with questions.

Are Health Screenings Covered by Insurance?

In many cases, preventive screenings are fully covered by health insurance under the Affordable Care Act. This includes tests for:

• Blood pressure

• Cholesterol

• Diabetes

• Certain cancers

Check with your insurance provider or ask your pharmacy team if you’re unsure. Even if you don’t have insurance, some pharmacies offer low-cost or free screenings during health events or wellness campaigns.

The Role of Pharmacies in Health Screenings

Many pharmacies now offer on-site health screenings, making it easy to monitor your wellness without visiting a doctor’s office. These services are often:

• Walk-in friendly (no appointment needed)

• Fast and convenient

• Affordable

Your pharmacy team can:

• Perform the test

• Explain your results

• Recommend next steps (such as a follow-up with your doctor)

Some pharmacies may also track your screening results over time, helping you stay on top of your health goals.

Common Questions About Health Screenings

Are screenings the same as diagnostic tests?

No. Screenings look for risk, even in healthy people. If a screening finds something unusual, a diagnostic test may follow to confirm a condition.

How often should I get screened?

It depends on your health status and age. As a rule of thumb, have at least an annual wellness check, and discuss your needs with a healthcare provider.

Can screenings prevent disease?

While screenings don’t prevent disease directly, they lead to early action, which can prevent complications or stop diseases from worsening.

Staying on Track with Screenings

To stay proactive with your health:

• Schedule routine screenings annually

• Track your results and share them with your doctor

• Follow up on abnormal results right away

• Ask questions and understand your numbers

Your pharmacy team can be a valuable resource for scheduling reminders, explaining test outcomes, and helping you make informed decisions.
